answer:if there are no external forces acting on the object

Explanation:

under what conditions would a scale record a weight for an object which is equal to the magnitude of the gravitational force on the object?

If gravity and the normal reaction force are the only forces acting on the body, and the body is at rest or moving at constant velocity, the normal force and the weight are equal and opposite. Also if there are no influence of external forces

and air resistance is negligible.

from newtons law of motion which states that the rate of change in momentum is directly proportional to the force applied

f=km(v-u)/t

f=kma

where k is the constant and  equal to 1

f=ma

In a non accelerated frame, also called inertial frame, when no additional forces are acting upon the body.

For instance, a scale in free fall will not record the weight, but zero, like the astronauts. But also, if someone is pulling the object or pushing it, the scale will record some other value.

You measure the power delivered by a battery to be 5.83 W when it is connected in series with two equal resistors. How much powe
BabaBlast [244]

Answer:

P = 23.32 W

Explanation:

In series  

equivalent Resistance

R(eq)=R+R=2R

In parallel equivalent resistance

R(eq) = R*R/(R+R) =R/2

since.

power

P=V² / R

in series

⇒V = √(P*R)

=√(5.83*2R )

=√(11.66R)

in parallel

P = V² / R(eq)

=(√(11.66R)²) / (R/2)

P=11.66 * R * 2/R

P = 23.32 W

I need help with the table, which is speed and velocity and acceleration
likoan [24]
The first box is Acceleration
the second box is Speed
the third box is Speed
the fourth box is velocity
the fifth box is Speed.

The reason the first box is acceleration is because let's say you are about to go up a hill you need to add acceleration to make it up the hill, I was going to say speed but it wouldn't said what mph was. 

The reason the second, third,and fifth box is speed is because it is telling up that an object is going _mph (the blank is where you put your estimate of speed of an object). 

The reason the fourth box is velocity is because velocity is both magnitude and direction so in the fourth box it says that the race car made a slight left turn which is a direction that the car is going in. 

Hope this helped :)
Have a great day
